 WARNING! 

WARNING! All refrigerant discharged from this unit must

be recovered WITHOUT EXCEPTION. Technicians must follow industry accepted guidelines and all local, state, and federal statutes for the recovery and disposal of refrigerants. If a compressor is removed from this unit, refrigerant circuit oil will remain in the compressor. To avoid leakage of compressor oil, refrigerant lines of the compressor must be sealed after it is removed.

Inspection - Upon receipt of the equipment, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the packaging of each unit, and inspect each unit for damage. Ensure that the carrier makes proper notation of any shortages or damage on all copies of the freight bill and completes a common carrier inspection report. Concealed damage not discovered during unloading must be reported to the carrier within 15 days of receipt of shipment. If not ﬁ led within 15 days, the freight company can deny the claim without recourse.

Note: It is the responsibility of the purchaser to ﬁ le all necessary claims with the carrier. Notify your equipment supplier of all damage within ﬁ fteen (15) days of shipment.

Storage - Equipment should be stored in its original

packaging in a clean, dry area. Store units in an upright position at all times. Stack units a maximum of 3 units high.

Unit Protection - Cover units on the job site with either the original packaging or an equivalent protective covering. Cap the open ends of pipes stored on the job site. In areas where painting, plastering, and/or spraying has not been completed, all due precautions must be taken to avoid physical damage to the units and contamination by foreign material. Physical damage and contamination may prevent proper start-up and may result in costly equipment clean-up.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Examine all pipes, ﬁ ttings, and valves before installing any of the system components. Remove any dirt or debris found in or on these components.

Pre-Installation - Installation, Operation, and Maintenance instructions are provided with each unit. Horizontal equipment is designed for installation above false ceiling or in a ceiling plenum. Other unit conﬁ gurations are typically installed in a mechanical room. The installation site chosen should include adequate service clearance around the unit. Before unit start-up, read all manuals and become familiar with the unit and its operation. Thoroughly check the system before operation.

Prepare units for installation as follows:

1. Compare the electrical data on the unit nameplate with ordering and shipping information to verify that the correct unit has been shipped.

2. Keep the cabinet covered with the original packaging until installation is complete and all plastering, painting, etc. is ﬁ nished.

3. Verify refrigerant tubing is free of kinks or dents and that it does not touch other unit components.

4. Inspect all electrical connections. Connections must be clean and tight at the terminals.

5. Remove any blower support packaging (water-to-air units only).

6. Loosen compressor bolts on units equipped with compressor spring vibration isolation until the compressor rides freely on the springs. Remove shipping restraints. (No action is required for compressors with rubber grommets.)

7. Some airﬂ ow patterns are ﬁ eld convertible (horizontal units only). Locate the airﬂ ow conversion section of this IOM.

8. Locate and verify any hot water generator (HWG), hanger, or other accessory kit located in the compressor section or blower section.

General Information

 CAUTION! 

CAUTION! All three phase scroll compressors must have

direction of rotation veriﬁ ed at start-up. Veriﬁ cation is achieved by checking compressor Amp draw. Amp draw will be substantially lower compared to nameplate values. Additionally, reverse rotation results in an elevated sound level compared to correct rotation. Reverse rotation will result in compressor internal overload trip within several minutes. Verify compressor type before proceeding.

 CAUTION! 

CAUTION! DO NOT store or install units in corrosive

environments or in locations subject to temperature or humidity extremes (e.g., attics, garages, rooftops, etc.). Corrosive conditions and high temperature or humidity can signiﬁ cantly reduce performance, reliability, and service life. Always move and store units in an upright position. Tilting units on their sides may cause equipment damage.

 CAUTION! 

CAUTION! CUT HAZARD - Failure to follow this caution may

result in personal injury. Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing, safety glasses and gloves when handling parts and servicing heat pumps.

NOTICE! Failure to remove shipping brackets from spring-mounted compressors will cause excessive noise, and could cause component failure due to added vibration.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Horizontal Unit Location

Units are not designed for outdoor installation. Locate the unit in an INDOOR area that allows enough space for service personnel to perform typical maintenance or repairs without removing unit from the ceiling. Horizontal units are typically installed above a false ceiling or in a ceiling plenum. Never install units in areas subject to freezing or where humidity levels could cause cabinet condensation (such as unconditioned spaces subject to 100% outside air). Consideration should be given to access for easy removal of the ﬁ lter and access panels. Provide sufﬁ cient room to make water, electrical, and duct connection(s).

If the unit is located in a conﬁ ned space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered door, etc. Any access panel screws that would be difﬁ cult to remove after the unit is installed should be removed prior to setting the unit. Refer to Figure 3 for an illustration of a typical installation. Refer to unit submittal data or engineering design guide for dimensional data.

Conform to the following guidelines when selecting unit location:

1. Provide a hinged access door in concealed-spline or plaster ceilings. Provide removable ceiling tiles in T-bar or lay-in ceilings. Refer to horizontal unit dimensions for speciﬁ c series and model in unit submittal data. Size the access opening to accommodate the service technician during the removal or replacement of the compressor and the removal or installation of the unit itself.

2. Provide access to hanger brackets, water valves and ﬁ ttings. Provide screwdriver clearance to access panels, discharge collars and all electrical connections.

3. DO NOT obstruct the space beneath the unit with piping, electrical cables and other items that prohibit future removal of components or the unit itself.

4. Use a manual portable jack/lift to lift and support the weight of the unit during installation and servicing.

Horizontal Installation

Mounting Horizontal Units

Horizontal units have hanger kits pre-installed from the factory as shown in Figure 1. Figure 3 shows a typical horizontal unit installation.

Horizontal heat pumps are typically suspended above a ceiling or within a sofﬁ t using ﬁ eld supplied, threaded rods sized to support the weight of the unit.

Use four (4) ﬁ eld supplied threaded rods and factory provided vibration isolators to suspend the unit. Hang the unit clear of the ﬂ oor slab above and support the unit by the mounting bracket assemblies only. DO NOT attach the unit ﬂ ush with the ﬂ oor slab above.

Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. On small units (less than 2.5 tons/8.8kW) ensure that unit pitch does not cause condensate leaks inside the cabinet.

Air Coil - To obtain maximum performance, the air coil should be cleaned before start-up. A 10% solution of dishwasher detergent and water is recommended for both sides of the coil. A thorough water rinse should follow. UV based anti-bacterial systems may damage

coated air coils.

Notice! Installation Note - Ducted Return: Many

horizontal WSHPs are installed in a return air ceiling plenum application (above ceiling). Vertical WSHPs are commonly installed in a mechanical room with free return (e.g. louvered door). Therefore, ﬁ lter rails are the industry standard and are included on ClimateMaster commercial heat pumps for the purposes of holding the ﬁ lter only. For ducted return applications, the ﬁ lter rail must be removed and replaced with a duct ﬂ ange or ﬁ lter rack. Canvas or ﬂ exible connectors should also be used to minimize vibration between the unit and ductwork.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Overview - Horizontal units can be ﬁ eld converted between side (straight) and back (end) discharge using the instructions below.

Note: It is not possible to ﬁ eld convert return air between left or right return models due to the necessity of refrigeration copper piping changes.

Preparation - It is best to ﬁ eld convert the unit on the

ground before hanging. If the unit is already hung it should be taken down for the ﬁ eld conversion.

Side to Back Discharge Conversion

1. Place unit in well lit area. Remove the screws as shown in Figure 4 to free top panel and discharge panel.

2. Lift out the access panel and set aside. Lift and rotate the discharge panel to the other position as shown, being careful with the blower wiring.

3. Check blower wire routing and connections for tension or contact with sheet metal edges. Re-route if necessary.

4. Check refrigerant tubing for contact with other components.

5. Reinstall top panel and screws noting that the location for some screws will have changed.

6. Manually spin the fan wheel to ensure that the wheel is not rubbing or obstructed.

7. Replace access panels.

Back to Side Discharge Conversion - If the discharge is changed from back to side, use above instruction noting that illustrations will be reversed.

Left vs. Right Return - It is not possible to ﬁ eld convert return air between left or right return models due to the necessity of refrigeration copper piping changes. However, the conversion process of side to back or back to side discharge for either right or left return conﬁ guration is the same. In some cases, it may be possible to rotate the entire unit 180 degrees if the return air connection needs to be on the opposite side. Note

that rotating the unit will move the piping to the other end of the unit.

Duct System Installatio

Horizontal Installation

Condensate Piping - Horizontal Units - A condensate

drain line must be installed and pitched away for the unit to allow for proper drainage. This connection must meet all local plumbing/building codes.

Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. On small units (less than 2.5 tons/8.8 kW), ensure that unit pitch does not cause condensate leaks inside the cabinet.

Install condensate trap at each unit with the top of the trap positioned below the unit condensate drain connection as shown in Figure 6. Design the depth of the trap (water-seal) based upon the amount of ESP capability of the blower (where 2 inches [51mm] of ESP capability requires 2 inches [51mm] of trap depth). As a general rule, 1-1/2 inch [38mm] trap depth is the minimum.

Each unit must be installed with its own individual trap and connection to the condensate line (main) or riser. Provide a means to ﬂ ush or blow out the condensate line. DO NOT install units with a common trap and/or vent.

ರ

* Some units include a painted drain connection. Using a threaded pipe or similar device to clear any excess paint accumulated inside this fitting may ease final drain line installation.

 CAUTION! 

CAUTION! Ensure condensate line is pitched toward drain

1/8 inch per ft [11mm per m] of run.

Always vent the condensate line when dirt or air can collect in the line or a long horizontal drain line is required. Also vent when large units are working against higher external static pressure than other units connected to the same condensate main since this may cause poor drainage for all units on the line. WHEN A

VENT IS INSTALLED IN THE DRAIN LINE, IT MUST BE LOCATED AFTER THE TRAP IN THE DIRECTION OF THE CONDENSATE FLOW.

Duct System Installation - Proper duct sizing and design

is critical to the performance of the unit. The duct system should be designed to allow adequate and even airﬂ ow through the unit during operation. Air ﬂ ow through the unit MUST be at or above the minimum stated airﬂ ow for the unit to avoid equipment damage. Duct systems should be designed for quiet operation. Refer to Figure 3 for horizontal duct system details or Figure 8 for vertical duct system details. A ﬂ exible connector is recommended for both discharge and return air duct connections on metal duct systems to eliminate the transfer of vibration to the duct system. To maximize sound attenuation of the unit blower, the supply and return plenums should include internal ﬁ berglass duct liner or be constructed from ductboard for the ﬁ rst few feet. Application of the unit to uninsulated ductwork in an unconditioned space is not recommended, as the unit’s performance may be adversely affected.

At least one 90° elbow should be included in the supply duct to reduce air noise. If air noise or excessive air ﬂ ow is a problem, the blower speed can be changed. For airﬂ ow charts, consult submittal data for the series and model of the speciﬁ c unit.

If the unit is connected to existing ductwork, a previous check should have been made to ensure that the ductwork has the capacity to handle the airﬂ ow required for the unit. If ducting is too small, as in the replacement of a heating only system, larger ductwork should be installed. All existing ductwork should be checked for leaks and repaired as necessary.

1. Install the unit on a piece of rubber, neoprene orother mounting pad material for sound isolation. The pad should be at least 3/8” [10mm] to 1/2” [13mm] in thickness. Extend the pad beyond all four edges of the unit.

2. Provide adequate clearance for ﬁ lter replacement and drain pan cleaning. Do not block ﬁ lter access with piping, conduit or other materials. Refer to unit submittal data or engineering design guide for dimensional data.

3. Provide access for fan and fan motor maintenance and for servicing the compressor and coils without removing the unit.

4. Provide an unobstructed path to the unit within the closet or mechanical room. Space should be sufﬁ cient to allow removal of the unit, if necessary.

Sound Attenuation for Vertical Units - Sound

attenuation is achieved by enclosing the unit within a small mechanical room or a closet. Additional measures for sound control include the following:

1. Mount the unit so that the return air inlet is 90° to the return air grille. Refer to Figure 9. Install a sound bafﬂ e as illustrated to reduce line-of sight sound transmitted through return air grilles.

2. Mount the unit on a rubber or neoprene isolation pad to minimize vibration transmission to the building structure.

Condensate Piping for Vertical Units - A condensate

line must be installed and pitched away from the unit to allow for proper drainage. This connection must meet all local plumbing/building codes. Vertical units utilize a condensate hose inside the cabinet as a trapping loop; therefore an external trap is not necessary. Figure 10a shows typical condensate connections. Figure 10b illustrates the internal trap for a typical vertical heat pump. Each unit must be installed with its own individual vent (where necessary) and a means to ﬂ ush or blow out the condensate drain line. Do not install units with a common trap and/or vent.

Installation of Supply and Return Piping

Follow these piping guidelines.

1. Install a drain valve at the base of each supply and return riser to facilitate system ﬂ ushing.

2. Install shut-off / balancing valves and unions at each unit to permit unit removal for servicing.

3. Place strainers at the inlet of each system circulating pump.

4. Select the proper hose length to allow slack between connection points. Hoses may vary in length by +2% to -4% under pressure.

5. Refer to Table 1. Do not exceed the minimum bend radius for the hose selected. Exceeding the minimum bend radius may cause the hose to collapse, which reduces water ﬂ ow rate. Install an angle adapter to avoid sharp bends in the hose when the radius falls below the required minimum.

Piping Installation

 WARNING! 

WARNING! Polyolester Oil, commonly known as POE oil, is

a synthetic oil used in many refrigeration systems including those with HFC-410A refrigerant. POE oil, if it ever comes in contact with PVC or CPVS piping, may cause failure of the PVC/CPVC. PVC/CPVC piping should never be used as supply or return water piping with water source heat pump products containing HFC-410A as system failures and property damage may result.

 CAUTION! 

CAUTION! Corrosive system water requires corrosion

resistant ﬁ ttings and hoses, and may require water treatment.

 CAUTION! 

CAUTION! Do not bend or kink supply lines or hoses.

Insulation is not required on loop water piping except where the piping runs through unheated areas, outside the building or when the loop water temperature is below the minimum expected dew point of the pipe ambient conditions. Insulation is required if loop water temperature drops below the dew point (insulation is required for ground loop applications in most climates).

Pipe joint compound is not necessary when Teﬂ on® thread tape is pre-applied to hose assemblies or when ﬂ ared-end connections are used. If pipe joint compound is preferred, use compound only in small amounts on the external pipe threads of the ﬁ tting adapters. Prevent sealant from reaching the ﬂ ared surfaces of the joint.

Note: When antifreeze is used in the loop, ensure that it is compatible with the Teﬂ on® tape or pipe joint compound that is applied.

Maximum allowable torque for brass ﬁ ttings is 30 ft-lbs [41 N-m]. If a torque wrench is not available, tighten ﬁ nger-tight plus one quarter turn. Tighten steel ﬁ ttings as necessary.

Optional pressure-rated hose assemblies designed speciﬁ cally for use with ClimateMaster units are available. Similar hoses can be obtained from alternate suppliers. Supply and return hoses are ﬁ tted with swivel-joint ﬁ ttings at one end to prevent kinking during installation.

vFlow™ Heat Pump Applications Overview

vFlow™ is a revolutionary new, intelligent, and efﬁ cient way to circulate water (or water plus antifreeze) using internal, variable speed water ﬂ ow control. The factory installed high efﬁ ciency variable speed pumps uses almost half the wattage of traditional ﬁ xed speed pump. vFlow™ technology improves the life expectancy of the unit by reducing the amount of energy required to optimize the ﬂ ow of water throughout the system and also reduces the space, cost, and labor required to install external water ﬂ ow control mechanisms (ﬂ ow controllers, solenoid and ﬂ ow control valves).

vFlow™ Conﬁ gurations:

1. Low System Pressure Drop Modulating Motorized Valve – Typical for External Central Pumping.

Primarily for use on multi-unit applications with central

pumping. With this option the unit includes a low pressure drop, high Cv modulating motorized water valve that is controlled by the DXM2 control based on the difference in the entering and leaving water temperature delta T. This valve is a standard factory installed feature for the

TZ unit.

2. High System Pressure Drop Modulating Motorized

Valve – Typical for High Pressure Water System such as Water Well Pumps.

With this option the unit includes a high pressure

drop modulating water valve that is controlled by the DXM2 control based on the difference in the entering and leaving water temperature delta T. A low Cv valve is used to provide more precise control against high system pressure differential type of loops. This valve is a factory installed option for the TZ unit and when selected replaces the modulating valve.

3. Standard Head Variable Pump – Typical for Multiple

Unit Central Pumping.

With this option the unit includes an internal variable

speed pump that is best suited to low pressure drop systems such as primary/secondary pumping. The pump speed is controlled by the DXM2 control based on the difference in the entering and leaving water temperature delta T. This pump includes an internal check valve for multiple unit installations.

This pump is a factory installed option for the TZ unit

and when selected replaces the modulating valve.

4. High Head Variable Pump – Typical for Individual

Unit Pumping.

With this option the unit includes an internal variable

speed pump that is capable of higher system pressure drops. The pump speed is controlled by the DXM2 control based on the difference in the entering and leaving water temperature delta T. This pump includes

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Commercial Water Loop Applications

Commercial systems typically include a number of units connected to a common piping system. Any unit plumbing maintenance work can introduce air into the piping system; therefore air elimination equipment is a major portion of the mechanical room plumbing. Consideration should be given to insulating the piping surfaces to avoid condensation. ClimateMaster recommends unit insulation any time the water temperature is expected to be below 60ºF (15.6ºC). Metal to plastic threaded joints should never be used due to their tendency to leak over time.

Teﬂ o n® tape thread sealant is recommended to minimize internal fouling of the heat exchanger. Do not over tighten connections and route piping so as not to interfere with service or maintenance access. Hose kits are available from ClimateMaster in different conﬁ gurations for connection between the unit and the piping system. Depending upon selection, hose kits may include shut off valves, P/T plugs for performance measurement, high pressure stainless steel braided hose, “Y” type strainer with blow down valve, and/or “J” type swivel connection.

Water-Loop Heat Pump Applications

The piping system should be ﬂ ushed to remove dirt, piping chips, and other foreign material prior to operation (see “Piping System Cleaning and Flushing Procedures” in this manual). The ﬂ ow rate is usually set between 2.25 and 3.5 gpm per ton [2.9 and 4.5 l/m per kW] of cooling capacity. ClimateMaster recommends 3 gpm per ton [3.9 l/m per kW] for most applications of water loop heat pumps. To ensure proper maintenance and servicing, P/T ports are imperative for temperature and ﬂ ow veriﬁ cation, as well as performance checks.

Water loop heat pump (cooling tower/boiler) systems typically utilize a common loop, maintained between 60 - 90°F [16 - 32°C]. The use of a closed circuit evaporative cooling tower with a secondary heat exchanger between the tower and the water loop is recommended. If an open type cooling tower is used continuously, chemical treatment and ﬁ ltering will be necessary.

Ground-Loop Heat Pump Applications

 CAUTION! 

CAUTION! The following instructions represent industry accepted installation practices for closed loop earth coupled heat pump systems. Instructions are provided to assist the contractor in installing trouble free ground loops. These instructions are recommendations only. State/provincial and local codes MUST be followed and installation MUST conform to ALL applicable codes. It is the responsibility of the installing contractor to determine and comply with ALL applicable codes and regulations.

 CAUTION! 

CAUTION! Ground loop applications require extended range equipment and optional refrigerant/water circuit insulation.

Pre-Installation

Prior to installation, locate and mark all existing underground utilities, piping, etc. Install loops for new construction before sidewalks, patios, driveways, and other construction has begun. During construction, accurately mark all ground loop piping on the plot plan as an aid in avoiding potential future damage to the installation.

Piping Installation

The typical closed loop ground source system is shown in Figure 13. All earth loop piping materials should be limited to polyethylene fusion only for in-ground sections of the loop. Galvanized or steel ﬁ ttings should not be used at any time due to their tendency to corrode. All plastic to metal threaded ﬁ ttings should be avoided due to their potential to leak in earth coupled applications. A ﬂ anged ﬁ tting should be substituted. P/T plugs should be used with units that do not include vFlow so that ﬂ ow can be measured using the pressure drop of the unit heat exchanger. Units equipped with any of the four vFlow conﬁ gurations have built in Schrader ports. Water temperature may be viewed on the iGate communicating thermostat.

Earth loop temperatures can range between 25 and 110°F [-4 to 43°C]. Flow rates between 2.25 and 3 gpm [2.41 to

3.23 l/m per kW] of cooling capacity is recommended in

these applications.

Test individual horizontal loop circuits before backﬁ lling. Test vertical U-bends and pond loop assemblies prior to installation. Pressures of at least 100 psi [689 kPa] should be used when testing. Do not exceed the pipe pressure rating. Test entire system when all loops are assembled.

Flushing the Earth Loop

Upon completion of system installation and testing, ﬂ ush the system to remove all foreign objects and purge to remove all air.

Antifreeze

n areas where minimum entering loop temperatures drop below 40°F [5°C] or where piping will be routed through areas subject to freezing, antifreeze is required. Alcohols and glycols are commonly used as antifreeze; however your local sales ofﬁ ce should be consulted to determine the antifreeze best suited to your area. Freeze protection should be maintained to 15°F [9°C] below the lowest expected entering loop temperature. For example, if 30°F [-1°C] is the minimum expected entering loop temperature, the leaving loop temperature would be 22 to 25°F [-6 to -4°C] and freeze protection should be at 15°F [-10°C]. Calculation is as follows: 30°F - 15°F = 15°F [-1°C - 9°C = -10°C].

All alcohols should be premixed and pumped from a reservoir outside of the building when possible or introduced under the water level to prevent fumes. Calculate the total volume of ﬂ uid in the piping system. Then use the percentage by volume shown in table 2 for the amount of antifreeze needed. Antifreeze concentration should be checked from a well mixed sample using a hydrometer to measure speciﬁ c gravity.

Low Water Temperature Cutout Setting - DXM2 Control

When antifreeze is selected, the LT1 jumper (JW3) should be clipped to select the low temperature (antifreeze

loop piping is shown in accompanying illustration. Shut off valves should be included for ease of servicing. Boiler drains or other valves should be “tee’d” into the lines to allow acid ﬂ ushing of the heat exchanger. Shut off valves should be positioned to allow ﬂ ow through the coax via the boiler drains without allowing ﬂ ow into the piping system. P/T plugs should be used with units that do not include vFlow™ so that flow can be measured using the pressure drop of the unit heat exchanger. Units equipped with any of the four vFlow™ configurations have built in Schrader ports. Water temperature may be viewed on the iGate communicating thermostat. Supply and return water piping materials should be limited to copper, PE, or similar material. PVC or CPVC should never be used as they are incompatible with the POE oils used in HFC-410A products and piping system failure and property damage may result.

WARNING! Polyolester Oil, commonly known as POE oil, is

Water quantity should be plentiful and of good quality. Consult table 3 for water quality guidelines. The unit can be ordered with either a copper or cupro-nickel water heat exchanger. Consult Table 3 for recommendations. Copper is recommended for closed loop systems and open loop ground water systems that are not high in mineral content or corrosiveness. In conditions anticipating heavy scale formation or in brackish water, a cupro-nickel heat exchanger is recommended. In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, an open loop system is not recommended. Heat exchanger coils may over time lose heat exchange capabilities due to build up of mineral deposits. Heat exchangers must only be serviced by a qualiﬁ ed technician, as acid and special pumping equipment is required. Desuperheater coils can likewise become scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional acid ﬂ ushing. In some cases, the desuperheater option should not be recommended due to hard water conditions and additional maintenance required.

Water Quality Standards

- Table 3 should be consulted for water quality requirements. Scaling potential should be assessed using the pH/Calcium hardness method. If the pH <7.5 and the calcium hardness is less than 100 ppm, scaling potential is low. If this method yields numbers out of range of those listed, the Ryznar Stability and Langelier Saturation indecies should be calculated. Use the appropriate scaling surface temperature for the application, 150°F [66°C] for direct use (well water/open loop) and DHW (desuperheater); 90°F [32°F] for indirect use. A monitoring plan should be implemented in these probable scaling situations. Other water quality issues such as iron fouling, corrosion prevention and erosion and clogging should be referenced in Table 3.

Expansion Tank and Pump

- Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. The expansion tank should be sized to provide at least one minute continuous run time of the pump using its drawdown capacity rating to prevent pump short cycling. Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local building codes (e.g. recharge well, storm sewer, drain ﬁ eld, adjacent stream or pond, etc.). Most local codes forbid the use of sanitary sewer for disposal. Consult your local building and zoning department to assure compliance in your area.

Water Control Valve

Units without vFlow™

- Always maintain water pressure in the heat exchanger by placing the water control valve(s) on the discharge line to prevent mineral precipitation during the off-cycle. Pilot operated slow closing valves are recommended to reduce water hammer. If water hammer persists, a mini-expansion tank can be mounted on the piping to help absorb the excess hammer shock. Ensure that the total ‘VA’ draw of the valve can be supplied by the unit transformer. For instance, a slow closing valve can draw up to 35VA. This can overload smaller 40 or 50 VA transformers depending on the other controls in the circuit. A typical pilot operated solenoid valve draws approximately 15VA. Note the special wiring diagrams for slow closing valves (shown later in this manual).

ClimateMaster Water-Source Heat Pumps

Page 21

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Flow Regulation

Units without vFlow™

- Flow regulation can be accomplished by two methods. One method of ﬂ ow regulation involves simply adjusting the ball valve or water control valve on the discharge line. Measure the pressure drop through the unit heat exchanger, and determine ﬂ ow rate from Tables 8a through 8e. Since the pressure is constantly varying, two pressure gauges may be needed. Adjust the valve until the desired ﬂ ow of 1.5 to 2 gpm per ton [2.0 to 2.6 l/m per kW] is achieved. A second method of ﬂ ow control requires a ﬂ ow control device mounted on the outlet of the water control valve. The device is typically a brass ﬁ tting with an oriﬁ ce of rubber or plastic material that is designed to allow a speciﬁ ed ﬂ ow rate. On occasion, ﬂ ow control devices may produce velocity noise that can be reduced by applying some back pressure from the ball valve located on the discharge line. Slightly closing the valve will spread the pressure drop over both devices, lessening the velocity noise.

All 208/230 voltage units are factory wired

General Line Voltage Wiring

power is the same voltage and phase shown on the unit serial plate. Line and low voltage wiring must be done in accordance with local codes or the National Electric Code, whichever is applicable.

Thermostat Connections - The thermostat will be wired to the DXM2 board located within the unit control box. Refer to the unit wiring diagram for speciﬁ c details.

Low Water Temperature Cutout Selection - The DXM2 control allows the ﬁ eld selection of low water (or waterantifreeze solution) temperature limit by clipping jumper JW3, which changes the sensing temperature associated with thermistor LT1. Note that the LT1 thermistor is located on the refrigerant line between the coaxial heat exchanger and expansion device (TXV). Therefore, LT1 is sensing refrigerant temperature, not water temperature, which is a better indication of how water ﬂ ow rate/ temperature is affecting the refrigeration circuit.

- Be sure the available

ELECTRICAL - LOW VOLTAGE WIRING

The factory setting for LT1 is for systems using water (30°F [-1.1°C] refrigerant temperature). In low water temperature (extended range) applications with antifreeze (most ground loops), jumper JW3 should be clipped as shown in Figure 17 to change the setting to 10°F [-12.2°C] refrigerant temperature, a more suitable temperature when using an antifreeze solution. All ClimateMaster units operating with entering water temperatures below 60°F [15.6°C] must include the optional water/refrigerant circuit insulation package to prevent internal condensation.

Unit Without vFlow™ - An external solenoid valve(s) should be used on ground water installations to shut off ﬂ ow to the unit when the compressor is not operating. A slow closing valve may be required to help reduce water hammer. Figure 18 shows typical wiring for a 24VAC external solenoid valve. Figures 19 and 20 illustrate typical slow closing water control valve wiring for Taco 500 series (ClimateMaster P/N AVM) and Taco SBV series valves. Slow closing valves take approximately 60 seconds to open (very little water will ﬂ ow before 45 seconds). Once fully open, an end switch allows the compressor to be energized. Only relay or triac based electronic thermostats should be used with slow closing valves. When wired as shown, the slow closing valve will operate properly with the following notations:

1. The valve will remain open during a unit lockout.

2. The valve will draw approximately 25-35 VA through the “Y” signal of the thermostat.

Note: This valve can overheat the anticipator of an electromechanical thermostat. Therefore, only relay or triac based thermostats should be used.

Two-stage Units

Tranquility® 22 two parallel valves for ground water applications to limit water use during ﬁ rst stage operation. For example, at 1.5 gpm/ton [2.0 l/m per kW], a TZ049 unit requires 6 gpm [23 l/m] for full load (2nd stage) operation, but only 4 gpm [15 l/m] during 1st stage operation. Since the unit will operate on ﬁ rst stage 80-90% of the time, signiﬁ cant water savings can be realized by using two parallel solenoid valves with two ﬂ ow regulators. In the example above, stage one solenoid would be installed with a 4 gpm [15 l/m] ﬂ ow regulator on the outlet, while stage two would utilize a 2 gpm [8 l/m] ﬂ ow regulator. When stage one is operating, the second solenoid valve will be closed. When stage two is operating, both valves will be open, allowing full load ﬂ ow rate.

Figure 21 illustrates piping for two-stage solenoid valves. Review ﬁ gures 18-20 for wiring of stage one valve. Stage two valve should be wired between terminal “Y2” and terminal “C.” NOTE: When EWT is below 50°F [10°C], 2 gpm per ton (2.6 l/m per kW) is required.

Thermostat Installation - The thermostat should be located on an interior wall in a larger room, away from supply duct drafts. DO NOT locate the thermostat in areas subject to sunlight, drafts or on external walls. The wire access hole behind the thermostat may in certain cases need to be sealed to prevent erroneous temperature measurement. Position the thermostat back plate against the wall so that it appears level and so the thermostat wires protrude through the middle

THE SMART SOLUTION FOR ENERGY EFFICIENCY

The ECM fan is controlled directly by the DXM2 control board that converts thermostat inputs and CFM settings to signals used by the ECM motor controller. To take full advantage of the ECM motor features, a communicating multi-stage thermostat should be used (ATC32U**).

The DXM2 control maintains a selectable operating airﬂ ow [CFM] for each heat pump operating mode. For each operating mode there are maximum and minimum airﬂ ow limits. See the ECM Blower Performance tables for the maximum, minimum, and default operating airﬂ ows.

Airﬂ ow levels are selected using the conﬁ guration menus of a communicating thermostat (ATC32U**) or diagnostic tool (ACDU**). The conﬁ guration menus allow the installer to independently select and adjust the operating airﬂ ow for each of the operating modes. Air ﬂ ow can be selected in 25 CFM increments within the minimum and maximum limits shown in the ECM Blower Performance Table. The blower operating modes include:

• First Stage Cooling (Y1 & O)

• Second Stage Cooling (Y1, Y2, & O)

• First Stage Cooling in Dehumidification Mode (Y1, O, & Dehumid)

• Second Stage Cooling in Dehumidification Mode (Y1, Y2, O, & Dehumid)

ECM Blower Control

The ramp down feature is eliminated during an ESD (Emergency Shut Down) situation. When the DXM2 ESD input is activated, the blower and all other control outputs are immediately de-activated.

The ramp down feature (also known as the heating or cooling “Off Delay”) is ﬁ eld selectable by the installer. The allowable range is 0 to 255 seconds.

Special Note for AHRI Testing:

To achieve rated airﬂ ow for AHRI testing purposes, it is necessary to change the CFM settings to rated airﬂ ow.

It is highly recommended that ATC32U** or ACDU** be used to set dehumidiﬁ cation mode electronically. Dehumidiﬁ cation can NOT be selected when using a non-communicating thermostat with a vFlow™ unit with Internal Flow Controller (pump). For dehumidiﬁ cation settings on other units using the non-communicating stat, refer to DXM2 AOM (part #97B0003N15).

The ECM motor includes “soft start” and “ramp down” features. The soft start feature is a gentle increase of motor rpm at blower start up. This creates a much quieter blower start cycle.

The ramp down feature allows the blower to slowly decrease rpm to a full stop at the end of each blower cycle. This creates a much quieter end to each blower cycle and adds overall unit efﬁ ciency.

DXM2 Control - For detailed control information, see DXM2 Application, Operation and Maintenance (AOM) manual (part # 97B0003N15).

Field Selectable Inputs - Test mode: Test mode allows the service technician to check the operation of the control in a timely manner. By momentarily pressing the TEST pushbutton, the DXM2 control enters a 20 minute test mode period in which all time delays are sped up 15 times. Upon entering test mode, the status LED display will change, either ﬂ ashing rapidly to indicate the control is in the test mode, or displaying a numeric ﬂ ash code representing the current airﬂ ow if an ECM blower is connected and operating. For diagnostic ease at conventional thermostats, the alarm relay will also cycle during test mode. The alarm relay will cycle on and off similar to the fault LED to indicate a code representing the last fault, at the thermostat. Test mode can be exited by pressing the TEST pushbutton for 3 seconds.

Retry Mode – If the control is attempting a retry of a fault, the fault LED will slow ﬂ ash (slow ﬂ ash = one ﬂ ash every 2 seconds) to indicate the control is in the process of retrying.

Field Conﬁ guration Options – Note: In the following ﬁ eld conﬁ guration options, jumper wires should be clipped ONLY when power is removed from the DXM2 control.

Water coil low temperature limit setting: Jumper 3 (JW3LT1 Low Temp) provides ﬁ eld selection of temperature limit setting for LT1 of 30°F or 10°F [-1°F or -12°C] (refrigerant temperature).

Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].

Alarm relay setting: Jumper 1 (JW1-AL2 Dry) provides ﬁ eld selection of the alarm relay terminal AL2 to be jumpered to 24VAC or to be a dry contact (no connection). Not Clipped = AL2 connected to R. Clipped = AL2 dry contact (no connection).

DXM2 Controls

DIP Switches – Note: In the following ﬁ eld conﬁ guration

options, DIP switches should only be changed when power is removed from the DXM2 control.

DIP Package #1 (S1) – DIP Package #1 has 8 switches and provides the following setup selections:

1.1 - Unit Performance Sentinel (UPS) disable: DIP Switch

1.1 provides ﬁ eld selection to disable the UPS feature.

On = Enabled. Off = Disabled.

1.2 - Compressor relay staging operation: DIP 1.2 provides selection of compressor relay staging operation. The compressor relay can be selected to turn on with a stage 1 or stage 2 call from the thermostat. This is used with dual stage units (2 compressors where 2 DXM2 controls are being used) or with master/ slave applications. In master/slave applications, each compressor and fan will stage according to its appropriate DIP 1.2 setting. If set to stage 2, the compressor will have a 3 second on-delay before energizing during a Stage 2 demand. Also, if set for stage 2, the alarm relay will NOT cycle during test mode.

On = Stage 1. Off = Stage 2.

1.3 - Thermostat type (heat pump or heat/cool): DIP 1.3 provides selection of thermostat type. Heat pump or heat/cool thermostats can be selected. When in heat/ cool mode, Y1 is the input call for cooling stage 1; Y2 is the input call for cooling stage 2; W1 is the input call for heating stage 1; and O/W2 is the input call for heating stage 2. In heat pump mode, Y1 is the input call for compressor stage 1; Y2 is the input call for compressor stage 2; W1 is the input call for heating stage 3 or emergency heat; and O/W2 is the input call for reversing valve (heating or cooling, depending upon DIP 1.4).

On = Heat Pump. Off = Heat/Cool.

1.4 - Thermostat type (O/B): DIP 1.4 provides selection of thermostat type for reversing valve activation. Heat pump thermostats with “O” output (reversing valve energized for cooling) or “B” output (reversing valve energized for heating) can be selected with DIP 1.4.

On = HP stat with “O” output for cooling. Off = HP stat with “B” output for heating.

1.5 - Dehumidiﬁ cation mode: DIP 1.5 provides selection of normal or dehumidiﬁ cation fan mode. In dehumidiﬁ cation mode, the fan speed relay will remain off during cooling stage 2. In normal mode, the fan speed relay will turn on during cooling stage 2.

On = Normal fan mode. Off = Dehumidiﬁ cation mode.

1.6 – DDC output at EH2: DIP 1.6 provides selection

for DDC operation. If set to “DDC Output at EH2,” the EH2 terminal will continuously output the last fault code of the controller. If set to “EH2 normal,” EH2 will operate as standard electric heat output.

On = EH2 Normal. Off = DDC Output at EH2.

1.7– Boilerless operation: DIP 1.7 provides selection of boilerless operation. In boilerless mode, the compressor is only used for heating when LT1 is above the temperature speciﬁ ed by the setting of DIP 1.8. Below DIP 1.8 setting, the compressor is not used and the control goes into emergency heat mode, staging on EH1 and EH2 to provide heating.

On = normal. Off = Boilerless operation.

1.8 – Boilerless changeover temperature: DIP

1.8 provides selection of boilerless changeover temperature setpoint. Note that the LT1 thermistor is sensing refrigerant temperature between the coaxial heat exchanger and the expansion device (TXV). Therefore, the 50°F [10°C] setting is not 50°F [10°C] water, but approximately 60°F [16°C] EWT.

On = 50°F [10°C]. Off = 40°F [16°C].

DIP Package #2 (S2) – A combination of dip switches

2.1, 2.2, 2.3, and 2.4, 2.5, 2.6 deliver conﬁ guration of ACC1 and ACC2 relay options respectively. See Table 7a for description and functionality.

2.7 – Auto dehumidiﬁ cation fan mode or high fan mode: DIP 2.7 provides selection of auto dehumidiﬁ cation fan mode or high fan mode. In auto dehumidiﬁ cation mode, the fan speed relay will remain off during cooling stage 2 IF the H input is active. In high fan mode, the fan enable and fan speed relays will turn on when the H input is active.

On = Auto dehumidiﬁ cation mode (default). Off = High fan mode.

2.8 – Special factory selection: DIP 2.8 provides special factory selection. Normal position is “On”. Do not change selection unless instructed to do so by the factory.

3.1 – Communications conﬁ guration: DIP 3.1 provides selection of the DXM2 operation in a communicating system. The DXM2 may operate as the Master of certain network conﬁ gurations. In most conﬁ gurations the DXM2 will operate as a master device.

On = Communicating Master device (default). Off = communicating Slave device.

3.2 – HWG Test Mode: DIP 3.2 provides forced operation of the HWG pump output, activating the HWG pump output for up to ﬁ ve minutes.

On = HWG test mode. Off = Normal HWG mode (default).

3.3 – HWG Temperature: DIP 3.3 provides the selection of the HWG operating setpoint.

On = 150°F [66°C]. Off = 125°F [52°C] (default).

3.4 – HWG Status: DIP 3.4 provides HWG operation control.

On = HWG mode enabled. Off = HWG mode disabled (default).

DXM2 Control Start-up Operation – The control will not operate until all inputs and safety controls are checked for normal conditions. The compressor will have a 5 minute anti-short cycle delay at power-up. The ﬁ rst time after power-up that there is a call for compressor, the compressor will follow a 5 to 80 second random start delay. After the random start delay and anti-short cycle delay, the compressor relay will be energized. On all subsequent compressor calls, the random start delay is omitted.

Unit Starting and Operating Conditions

Operating Limits

Environment – Units are designed for indoor installation only. Never install units in areas subject to freezing or where humidity levels could cause cabinet condensation (such as unconditioned spaces subject to 100% outside air).

Power Supply – A voltage variation of +/– 10% of nameplate utilization voltage is acceptable.

Determination of operating limits is dependent primarily upon three factors: 1) return air temperature. 2) water temperature, and 3) ambient temperature. When any one of these factors is at minimum or maximum levels, the other two factors should be at normal levels to ensure proper unit operation. Extreme variations in temperature and humidity and/or corrosive water or air will adversely affect unit performance, reliability, and service life. Consult Table 9a for operating limits.

Piping System Cleaning and Flushing

Piping System Cleaning and Flushing - Cleaning and

ﬂ ushing the WLHP piping system is the single most important step to ensure proper start-up and continued efﬁ cient operation of the system.

Follow the instructions below to properly clean and ﬂ ush the system:

1. Ensure that electrical power to the unit is disconnected.

2. Install the system with the supply hose connected directly to the return riser valve. Use a single length of ﬂ exible hose.

3. Open all air vents. Fill the system with water. DO NOT allow system to overﬂ ow. Bleed all air from the system. Pressurize and check the system for leaks and repair as appropriate.

4. Verify that all strainers are in place (ClimateMaster recommends a strainer with a #20 stainless steel wire mesh). Start the pumps, and systematically check each vent to ensure that all air is bled from the system.

5. Verify that make-up water is available. Adjust make-up water as required to replace the air which was bled from the system. Check and adjust the water/air level in the expansion tank.

6. Set the boiler to raise the loop temperature to approximately 86°F [30°C]. Open a drain at the lowest point in the system. Adjust the make-up water replacement rate to equal the rate of bleed.

7. Reﬁ ll the system and add trisodium phosphate in a proportion of approximately one pound per 150 gallons (.8 kg per 1000 l) of water (or other equivalent approved cleaning agent). Reset the boiler to raise the loop temperature to 100°F [38°C]. Circulate the solution for a minimum of 8 to 24 hours. At the end of this period, shut off the circulating pump and drain the solution. Repeat system cleaning if desired.

8. When the cleaning process is complete, remove the short-circuited hoses. Reconnect the hoses to the proper supply, and return the connections to each of the units. Reﬁ ll the system and bleed off all air.

9. Test the system pH with litmus paper. The system water should be in the range of pH 6.0 - 8.5 (see table 3). Add chemicals, as appropriate to maintain neutral pH levels.

10. When the system is successfully cleaned, ﬂ ushed,

reﬁ lled and bled, check the main system panels, safety cutouts and alarms. Set the controls to properly maintain loop temperatures.

DO NOT use “Stop Leak” or similar chemical agent in this system. Addition of chemicals of this type to the loop water will foul the heat exchanger and inhibit unit operation.

Note: The manufacturer strongly recommends all piping connections, both internal and external to the unit, be pressure tested by an appropriate method prior to any ﬁ nishing of the interior space or before access to all connections is limited. Test pressure may not exceed the maximum allowable pressure for the unit and all components within the water system. The manufacturer will not be responsible or liable for damages from water leaks due to inadequate or lack of a pressurized leak test, or damages caused by exceeding the maximum pressure rating during installation.

UNIT CHECKOUT

 Balancing/shutoff valves: Ensure that all isolation

valves are open and water control valves are wired.

 Line voltage and wiring: Verify that voltage is within

an acceptable range for the unit and wiring and fuses/breakers are properly sized. Verify that low voltage wiring is complete.

 Unit control transformer: Ensure that transformer has

the properly selected voltage tap.

 Entering water and air: Ensure that entering water

and air temperatures are within operating limits of Table 9a-b.

 Low water temperature cutout: Verify that low water

temperature cut-out on the DXM2 control is properly set.

 Unit fan: Manually rotate fan to verify free rotation

and ensure that blower wheel is secured to the motor shaft. Be sure to remove any shipping supports if needed. DO NOT oil motors upon startup. Fan motors are pre-oiled at the factory. Check unit fan speed selection and compare to design requirements.

 Condensate line: Verify that condensate line is open

and properly pitched toward drain.

 Water ﬂ ow balancing: Record inlet and outlet water

temperatures for each heat pump upon startup. This check can eliminate nuisance trip outs and high velocity water ﬂ ow that could erode heat exchangers.

 Unit air coil and ﬁ lters: Ensure that ﬁ lter is clean and

accessible. Clean air coil of all manufacturing oils.

 Unit controls: Verify that DXM2 ﬁ eld selection

options are properly set.

Unit and System Checkout

SYSTEM CHECKOUT

 System water temperature: Check water temperature

for proper range and also verify heating and cooling set points for proper operation.

 System pH: Check and adjust water pH if necessary

to maintain a level between 6 and 8.5. Proper pH promotes longevity of hoses and ﬁ ttings (see table 3).

 System ﬂ ushing: Verify that all hoses are connected

end to end when ﬂ ushing to ensure that debris bypasses the unit heat exchanger, water valves and other components. Water used in the system must be potable quality initially and clean of dirt, piping slag, and strong chemical cleaning agents. Verify that all air is purged from the system. Air in the system can cause poor operation or system corrosion.

 Cooling tower/boiler: Check equipment for proper

setpoints and operation.

 Standby pumps: Verify that the standby pump is

properly installed and in operating condition.

 System controls: Verify that system controls function

and operate in the proper sequence.

 Low water temperature cutout: Verify that low water

temperature cut-out controls are provided for the outdoor portion of the loop. Otherwise, operating problems may occur.

 System control center: Verify that the control center

and alarm panel have appropriate setpoints and are operating as designed.

 Miscellaneous: Note any questionable aspects of the

installation.

 CAUTION! 

CAUTION! Verify that ALL water control valves are open and

allow water ﬂ ow prior to engaging the compressor. Freezing of the coax or water lines can permanently damage the heat pump.

 CAUTION! 

CAUTION! To avoid equipment damage, DO NOT

leave system ﬁ lled in a building without heat during the winter unless antifreeze is added to the water loop. Heat exchangers never fully drain by themselves and will freeze unless winterized with antifreeze.

NOTICE! Failure to remove shipping brackets from spring-mounted compressors will cause excessive noise, and could cause component failure due to added vibration.

Unit Start-Up Procedure

Unit Start-up Procedure

1. Turn the thermostat fan position to “ON”. Blower should start.

2. Balance air ﬂ ow at registers.

3. Adjust all valves to their full open positions. Turn on the line power to all heat pumps.

4. Room temperature should be within the minimummaximum ranges of table 9b. During start-up checks, loop water temperature entering the heat pump should be between 60°F [16°C] and 95°F [35°C].

5. Two factors determine the operating limits of ClimateMaster heat pumps, (a) return air temperature, and (b) water temperature. When any one of these factors is at a minimum or maximum level, the other factor must be at normal level to ensure proper unit operation.

a. Adjust the unit thermostat to the warmest setting.

Place the thermostat mode switch in the “COOL” position. Slowly reduce thermostat setting until the compressor activates.

b. Check for cool air delivery at the unit grille within a

few minutes after the unit has begun to operate.

Note: Units have a ﬁ ve minute time delay in

the control circuit that can be eliminated by pushing the test button on the DXM2 control board.

c. Verify that the compressor is on and that the water

ﬂ ow rate is correct by measuring pressure drop through the heat exchanger using the P/T plugs and comparing to table 10.

d. Check the elevation and cleanliness of the

condensate lines. Dripping may be a sign of a blocked line. Check that the condensate trap is ﬁ lled to provide a water seal.

e. Refer to table 12. Check the temperature of both

entering and leaving water. If temperature is within range, proceed with the test. Verify correct water ﬂ ow by comparing unit pressure drop across the heat exchanger versus the data in table 10. Heat of rejection (HR) can be calculated and compared to submittal data capacity pages. The formula for HR for systems with water is as follows: HR (Btuh) = TD x GPM x 500,where TD is the temperature difference between the entering and leaving water, and GPM is the ﬂ ow rate in U.S. GPM, determined by comparing the pressure drop across the heat exchanger to table 10. In S-I units, the formula is as follows: HR (kW) = TD x l/s x 4.18.

f. Check air temperature drop across the air coil when

compressor is operating. Air temperature drop should be between 15

g. Turn thermostat to “OFF” position. A hissing noise

indicates proper functioning of the reversing valve.

°F and 25°F [

ClimateMaster Water-Source Heat Pumps

6. Allow ﬁ ve (5) minutes between tests for pressure to equalize before beginning heating test. a. Adjust the thermostat to the lowest setting. Place

the thermostat mode switch in the “HEAT” position.

b. Slowly raise the thermostat to a higher

temperature until the compressor activates.

c. Check for warm air delivery within a few minutes

after the unit has begun to operate.

d. Refer to table 12. Check the temperature of both

entering and leaving water. If temperature is within range, proceed with the test. If temperature is outside of the operating range, check refrigerant pressures and compare to table 11. Verify correct water ﬂ ow by comparing unit pressure drop across the heat exchanger versus the data in table 10. Heat of extraction (HE) can be calculated and compared to submittal data capacity pages. The formula for HE for systems with water is as follows:

HE (kW) = TD xGPM x 500, where TD is the

temperature difference between the entering and leaving water, and l/s is the ﬂ ow rate in U.S. GPM, determined by comparing the pressure drop across the heat exchanger to table 10. In S-I units, the formula is as follows: HE (kW) = TD x l/s x 4.18.

e. Check air temperature rise across the air coil when

compressor is operating. Air temperature rise should be between 20°F and 30°F [11°C and 17°C].

f. Check for vibration, noise, and water leaks.

7. If unit fails to operate, perform troubleshooting analysis (see troubleshooting section). If the check described fails to reveal the problem and the unit still does not operate, contact a trained service technician to ensure proper diagnosis and repair of the equipment.

8. When testing is complete, set system to maintain desired comfort level.

Note: If performance during any mode appears abnormal, refer to the DXM2 section or troubleshooting section of this manual. To obtain maximum performance, the air coil should be cleaned before start-up. A 10% solution of dishwasher detergent and water is recommended.

Preventive Maintenance

Water Coil Maintenance - (Direct ground water

applications only) If the system is installed in an area with a known high mineral content (125 P.P.M. or greater) in the water, it is best to establish a periodic maintenance schedule with the owner so the coil can be checked regularly. Consult the well water applications section of this manual for a more detailed water coil material selection. Should periodic coil cleaning be necessary, use standard coil cleaning procedures, which are compatible with the heat exchanger material and copper water lines. Generally, the more water ﬂ owing through the unit, the less chance for scaling. Therefore, 1.5 gpm per ton [1.6 l/m per kW] is recommended as a minimum ﬂ ow. Minimum ﬂ ow rate for entering water temperatures below 50°F [10°C] is 2.0 gpm per ton [2.2 l/m per kW].

Water Coil Maintenance - (All other water loop applications) Generally water coil maintenance is not needed for closed loop systems. However, if the piping is known to have high dirt or debris content, it is best to establish a periodic maintenance schedule with the owner so the water coil can be checked regularly. Dirty installations are typically the result of deterioration of iron or galvanized piping or components in the system. Open cooling towers requiring heavy chemical treatment and mineral buildup through water use can also contribute to higher maintenance. Should periodic coil cleaning be necessary, use standard coil cleaning procedures, which are compatible with both the heat exchanger material and copper water lines. Generally, the more water ﬂ owing through the unit, the less chance for scaling. However, ﬂ ow rates over 3 gpm per ton (3.9 l/m per kW) can produce water (or debris) velocities that can erode the heat exchanger wall and ultimately produce leaks.

Hot Water Generator Coils - See water coil maintenance for ground water units. If the potable water is hard or not chemically softened, the high temperatures of the desuperheater will tend to scale even quicker than the water coil and may need more frequent inspections. In areas with extremely hard water, a HWG is not recommended.

Filters - Filters must be clean to obtain maximum performance. Filters should be inspected every month under normal operating conditions and be replaced when necessary. Units should never be operated without a ﬁ lter.

Washable, high efﬁ ciency, electrostatic ﬁ lters, when dirty, can exhibit a very high pressure drop for the fan motor and reduce air ﬂ ow, resulting in poor performance. It is especially important to provide consistent washing of

ClimateMaster Water-Source Heat Pumps

these ﬁ lters (in the opposite direction of the normal air ﬂ ow) once per month using a high pressure wash similar to those found at self-serve car washes.

Condensate Drain - In areas where airborne bacteria may produce a “slimy” substance in the drain pan, it may be necessary to treat the drain pan chemically with an algaecide approximately every three months to minimize the problem. The condensate pan may also need to be cleaned periodically to ensure indoor air quality. The condensate drain can pick up lint and dirt, especially with dirty ﬁ lters. Inspect the drain twice a year to avoid the possibility of plugging and eventual overﬂ ow.

Compressor - Conduct annual amperage checks to ensure that amp draw is no more than 10% greater than indicated on the serial plate data.

Fan Motors - All units have lubricated fan motors. Fan motors should never be lubricated unless obvious, dry operation is suspected. Periodic maintenance oiling is not recommended, as it will result in dirt accumulating in the excess oil and cause eventual motor failure. Conduct annual dry operation check and amperage check to ensure amp draw is no more than 10% greater than indicated on serial plate data.

Air Coil - The air coil must be clean to obtain maximum performance. Check once a year under normal operating conditions and, if dirty, brush or vacuum clean. Care must be taken not to damage the aluminum ﬁ ns while cleaning. When the heat pump has experienced less than 100 operational hours and the coil has not had sufﬁ cient time to be “seasoned”, it is necessary to clean the coil with a mild surfactant such as Calgon to remove the oils left by manufacturing processes and enable the condensate to properly “sheet” off of the coil. CAUTION: Fin edges are sharp.

Cabinet - Do not allow water to stay in contact with the cabinet for long periods of time to prevent corrosion of the cabinet sheet metal. Generally, vertical cabinets are set up from the ﬂ oor a few inches [7 - 8 cm] to prevent water from entering the cabinet. The cabinet can be cleaned using a mild detergent.

Refrigerant System - To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Reference the operating charts for pressures and temperatures. Verify that air and water ﬂ ow rates are at proper levels before servicing the refrigerant circuit.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

General

If operational difﬁ culties are encountered, perform the preliminary checks below before referring to the troubleshooting charts.

• Verify that the unit is receiving electrical supply power.

• Make sure the fuses in the fused disconnect switches are intact.

After completing the preliminary checks described above, inspect for other obvious problems such as leaking connections, broken or disconnected wires, etc. If everything appears to be in order, but the unit still fails to operate properly, refer to the “DXM2 Troubleshooting Process Flowchart” or “Functional Troubleshooting Chart.”

DXM2 Board

DXM2 board troubleshooting in general is best summarized as verifying inputs and outputs. After inputs and outputs have been veriﬁ ed, board operation is conﬁ rmed and the problem must be elsewhere. Below are some general guidelines for troubleshooting the DXM2 control.

Field Inputs

Conventional thermostat inputs are 24VAC from the thermostat and can be veriﬁ ed using a voltmeter between C and Y1, Y2, W, O, G. 24VAC will be present at the terminal (for example, between “Y1” and “C”) if the thermostat is sending an input to the DXM2 board.

Proper communications with a thermostat can be veriﬁ ed using the Fault LED on the DXM2. If the control is NOT in the Test mode and is NOT currently locked out or in a retry delay, the Fault LED on the DXM2 will ﬂ ash very slowly (1 second on, 5 seconds off), if the DXM2 is properly communicating with the thermostat.

Tranquility

22 (TZ) Series

Revised: 01/21/13

Troubleshooting

Outputs

The compressor and reversing valve relays are 24VAC and can be veriﬁ ed using a voltmeter. For units with ECM blower motors, the DXM2 controls the motor using serial communications, and troubleshooting should be done with a communicating thermostat or diagnostic tool. The alarm relay can either be 24VAC as shipped or dry contacts for use with DDC controls by clipping the JW1 jumper. Electric heat outputs are 24VDC “ground sinking” and require a voltmeter set for DC to verify operation. The terminal marked “24VDC” is the 24VDC supply to the electric heat board; terminal “EH1” is stage 1 electric heat; terminal “EH2” is stage 2 electric heat. When electric heat is energized (thermostat is sending a “W” input to the DXM2 controller), there will be 24VDC between terminal “24VDC” and “EH1” (stage 1 electric heat) and/or “EH2” (stage 2 electric heat). A reading of 0VDC between “24VDC” and “EH1” or “EH2” will indicate that the DXM2 board is NOT sending an output signal to the electric heat board.

Test Mode

Test mode can be entered for 20 minutes by pressing the Test pushbutton. The DXM2 board will automatically exit test mode after 20 minutes.

 WARNING! 

WARNING! HAZARDOUS VOLTAGE! DISCONNECT ALL

ELECTRIC POWER INCLUDING REMOTE DISCONNECTS BEFORE SERVICING. Failure to disconnect power before servicing can cause severe personal injury or death.

Sensor Inputs

All sensor inputs are ‘paired wires’ connecting each component to the board. Therefore, continuity on pressure switches, for example can be checked at the board connector. The thermistor resistance should be measured with the connector removed so that only the impedance of the thermistor is measured. If desired, this reading can be compared to the thermistor resistance chart shown in Table 8. An ice bath can be used to check the calibration of the thermistor.

Troubleshooting (Continued)

Advanced Diagnostics

If a communicating thermostat or diagnostic tool (ACDU) is connected to the DXM2, additional diagnostic information and troubleshooting capabilities are available. The current status of all DXM2 inputs can be veriﬁ ed, including the current temperature readings of all temperature inputs. With a communicating thermostat the current status of the inputs can be accessed from the Service Information menu. In the manual operating mode, most DXM2 outputs can be directly controlled for system troubleshooting. With a communicating thermostat the manual operating mode can be accessed from the Installer menu. For more detailed information on the advanced diagnostics of the DXM2, see the DXM2 Application, Operation and Maintenance (AOM) manual (part #97B0003N15).

DXM2 Troubleshooting Process Flowchart/Functional Troubleshooting Chart

The “DXM2 Functional Troubleshooting Process Flowchart” is a quick overview of how to start diagnosing a suspected problem, using the fault recognition features of the DXM2 board. The “Functional Troubleshooting Chart” on the following page is a more comprehensive method for identifying a number of malfunctions that may occur, and is not limited to just the DXM2 controls. Within the chart are ﬁ ve columns:

• The “Fault” column describes the symptoms.

• Columns 2 and 3 identify in which mode the fault is likely to occur, heating or cooling.

• The “Possible Cause column” identifies the most likely sources of the problem.

• The “Solution” column describes what should be done to

correct the problem.

Modulating Valve Troubleshooting

Improper output setting

Verify the AO-2 jumper is in the 0-10V position

No valve operation

Check voltage to the valve

No valve output signal

Check DC voltage between AO2 and GND. Should be O when valve is off and between 3.3v and 10v when valve is on.

Replace valve if voltage and control signals are present at the valve and it does not operate

For DXM2 check for “O” RV setup not “B”.
